The goal of this research project was to systematically investigate how turbine spacing affects turbine and array power output, using small arrays of scaled model wind turbines. Realistically scaled models of 5MW offshore wind turbines were designed, fabricated and characterized with respect to performance. Wind turbine arrays of various configurations (e.g., arrays of 1xN, 1x9, 3x3 turbines) were then installed and tested in a high Reynolds number turbulent boundary layer in the UNH Flow Physics Facility. Turbine spacing was varied, power output, tip speed ratio and thrust of turbines were measured, and array power was correlated to array area. The data obtained can help improve the wind farm energy yield per unit cost, which is driven by a tradeoff between improved turbines spacing vs. increased cost due to larger ocean area used.
